DRAFT Professional Services Christopher Sandt, County Engineer, 919-245- Contract — Lake Orange Intake 2583 Tower Rehabilitation-Replacement Cy Stober, Planning Director, 919-245-2592 2. FY 2023-33 CIP Summary — Lake Orange Dam Rehabilitation 3. Schnabel Engineering South, P.C. Statement of Qualifications (SOQ) 4. Letter of Recommendation — RFQ 367-005414 PURPOSE: To approve a professional services contract in the amount of $288,000 with Schnabel Engineering South, P.C. for the Lake Orange Perimeter Survey project (hereafter the "Project"). BACKGROUND: The Lake Orange Dam (hereafter "the Dam") is located at 1221 Lake Orange Road in Hillsborough, North Carolina. The Dam was constructed in the late 1960s via an earthen berm and concrete spillway/channel across the East Fork of the Eno River so as to create Lake Orange, a +/-150-acre surface water impoundment located within the Neuse River basin. The primary uses of Lake Orange are public water supply and maintenance of minimum dry weather flows in the East Fork of the Eno River. Limited recreational activities on Lake Orange are permitted as secondary uses. Lake Orange has a normal pool elevation of 615 feet (Mean Sea Level) and has a drainage area of approximately 5,850 acres. The Dam structural height is approximately 40 feet with a normal pool freeboard of approximately 15 feet. The Dam crest length is approximately 1,100 feet, and the Dam crest width is approximately 16 feet. The original construction of the Dam was funded via issuance of County bonds. The County is the owner and operator of Lake Orange and the Dam. The Lake Orange reservoir is classified by the North Carolina Department of Environmental Quality (NCDEQ) as Water Supply II — Undeveloped (WS-II) surface waters, with additional NCDEQ classifications as High-Quality Waters (HQW) and Nutrient Sensitive Waters (NSW). Descriptions of North Carolina surface water classifications are viewable online at: https://deg.nc.gov/about/divisions/water-resources/planning/classification-standards. In 2011, the NCDEQ classified the Dam as a Class C (High Hazard) dam, as defined in 15A North Carolina Administrative Code (NCAC) 2K.0105 (Classification of Dams). The High Hazard classification of the Dam warrants that any/all proposed repairs or alterations to the Dam be reviewed and approved by NCDEQ prior to construction, as defined in 15A NCAC 02K.0201 2 (Obtaining Approval for Dam Construction, Repair, or Removal). The NCDEQ tracking number for the Dam is ORANG-005. The existing intake tower is original to the late 1960s construction of Lake Orange and has surpassed its useful design life. The Project will include but will not be limited to: a water control plan (e.g., an engineered temporary coffer dam or Owner-approved equal), a completely rehabilitated (or completely replaced) reinforced concrete intake tower — constructed in-situ — with all appurtenances, including but not limited to a tower security/intruder prevention gate, a pedestrian access walkway/bridge, site access safety measures inclusive of OSHA- compliant handrails, a primary lake drain gate/valve, a primary tower drain gate/valve, three (3) intermediate lake level control gates/valves, manual and/or automated drain gate/valve actuators, a lake level monitoring device (ultrasonic level gauge or Owner-approved equal), a permanent rain gauge, OSHA-compliant tower access manway(s) and fixed interior access ladder(s), programming and integration of applicable appurtenances to the County's existing Supervisory Control and Data Acquisition (SCADA) system, erosion and sedimentation control measures, and site restoration. All work for the Project will be conducted on property owned by Orange County. Prior to the commencement of work, Orange County staff will schedule and conduct a Neighborhood Information Meeting with affected Lake Orange residents and/or affected property owners to explain the Project and address any questions/inquiries/concerns from the public. No traffic control or site perimeter security measures will be required, as the existing intake tower is fully contained within County property. No Dam modifications are anticipated. The Project is part of Orange County's current (FY 2023-33) Capital Investment Plan (CIP) (see Attachment 2 for FY 2023-33 CIP Summary). On April 5, 2024, Orange County published a Request for Qualifications (RFQ) No. 367-005414 for the Project.

The lake's primary uses are public water supply as designated by North Carolina Department of Environmental Quality(NCDEQ)and maintenance of minimum(dry weather)flows in the Eno River,as defined within the Eno River Water Management Plan (a.k.a.the Eno River Capacity Use Agreement). The Lake Orange dam was classified by NCDEQ as a "High Hazard"dam in August 2011 which means that failure of the dam could result in severe property damage and/or possible loss of life downstream. The Orange County Engineering Division, in coordination with contracted technical consultants,performed a series of detailed inspections of the Lake Orange dam and its associated appurtenances(e.g. intake tower,erosion control barrier,emergency spillway,and concrete spillway channel)between late 2018 and early 2022. Those detailed inspections have identified numerous deficiencies,most of which are due to the extended ages of the 54-year-old structures. This CIP project represents a proactive, multi-year approach to repair these deficiencies by continuing to address the highest priority needs in FY2023-24, FY2024-25,and FY2025-26. Future fiscal year funding amounts will address the need for complete replacement of the existing intake tower in FY 2023-24 and complete replacement of the existing concrete spillway channel in FY 2025-26.This project represents the full cost of these repairs, but the county will seek federal infrastructure grants to reduce the cost of this project.

(Schnabel) is pleased to present our qualifications to provide professional engineering services for the Orange County (the County) Lake Orange Intake Tower Rehabilitation-Replacement project. The enclosed information demonstrates why the Schnabel team is the best choice for your project. For more than six decades, Schnabel has solved unique and complex engineering challenges while managing risk without sacrificing quality. Schnabel has assembled an unparalleled, world class team that will provide value to the County's staff with exceptional service from engineers with decades of dam engineering experience. There is no substitute for experience. Schnabel is well-acquainted with the County's Lake Orange Dam and Intake Tower where we have performed field investigations of the intake tower in 2020 and 2022, along with evaluation and design of repairs for the Lake Orange's auxiliary spillway. Schnabel is well positioned to quickly understand and respond to the relevant issues and site conditions. Familiarity with this site is a significant advantage. Schnabel is unique in that we have over 235 technical professionals dedicated to dam engineering and over 250 geoprofessionals with extensive experience in subsurface explorations, instrumentation installation and monitoring, and geotechnical engineering related to dams and ancillary structures -all of which are particularly relevant to this project. The quality of the engineering performed by our NC office has been recognized and awarded numerous regional and national engineering excellence awards. Our NC projects have won the prestigious Association of Dam Safety Officials (ASDSO) Rehabilitation Project of the Year award twice since 2012. The national award winning projects were the 2012 Lake Townsend Dam Project for the City of Greensboro, NC and the 2018 Hope Mill Dam Project for the Town of Hope Mills, NC. The local West Fork Eno Reservoir Expansion Project was awarded the American Council of Engineering Companies (ACEC)2023 National Honor Award and 2022 NC ACEC Engineering Excellence Honor Award. We are an industry leader in dam engineering. 15 Orange County, NC Lake Orange Intake Tower Rehabilitation-Replacement The project will be led by and performed by personnel from Schnabel's Greensboro, NC office, who will be responsible for overall project and client management, design of the intake tower rehabilitation or replacement, permitting support, assistance with bidding, and construction phase services. To complement our in-house capabilities, Schnabel has partnered with local subconsultants to perform environmental permitting (Three Oaks), and surveying (Pennoni). The subconsultants chosen for this project provide a team of highly trained and experienced personnel that will allow us to work seamlessly as one group. As the project progresses and the scope of the intake tower rehabilitation or replacement is better known, should additional subconsultants be needed (such as for geotechnical drilling from a barge), Schnabel has a network of local potential subconsultants that can be engaged to get the job done. Schnabel understands the concerns with the current intake tower and what is necessary to rehabilitate or replace it with a new long-term solution that meets regulatory requirements. Schnabel will work with the County to understand the performance needs of the intake tower so that an economical solution that meets those needs can be developed. Good communication will result in fine tuning the way we perform our services to your needs, thus improving the quality of deliverables that we provide to the Orange County. It is our understanding that the intake tower construction work will be done with an at least partially full reservoir, Schnabel has extensive experience with developing control of water plans and the design of temporary cofferdams to manage construction risks while keeping the benefits of a partially full reservoir. Leveraging our team's collective experience and knowledge will allow us to provide the County with tremendous value by better understanding the project staff, site protocols and safety standards, and enhancing schedule deadlines while managing risk and providing long term solutions. Should you have any questions or need additional information, please contact Samuel Kees, PE at (336)274-9456 or via email at skees@schnabel-eng.com. Schnabel welcomes the opportunity to meet with the County to discuss our qualifications, proposed approach and how we can best assist you with this project.

Survey - Pennoni is a nationwide multidisciplinary firm with the ability to approach engineering challenges from a wider spectrum of angles that most. The Raleigh office was formerly CH Engineering whose staff includes 5 licensed Professional Land Surveyors. As CH Engineering Pennoni has experience performing survey work at Lake Orange. d. SCOPE OF WORK & PROJECT UNDERSTANDING Lake Orange Dam (ORANG-005, NC-00773) is located in Cedar Grove, North Carolina and impounds the East Fork of the Eno River. The dam and reservoir are owned and maintained by Orange County, and they are used primarily for public water supply and water management within the East Fork of Eno River, secondary uses include private recreation. The dam is regulated by North Carolina Department of Environmental Quality NCDEQ Dam Safety as a medium-size, high hazard structure. According to the NCDEQ Dam Safety inventory, the dam was constructed in 1969. The dam is an approximately 30-foot high, 1,100-foot-long earthen embankment that impounds an approximately 140-acre lake at normal pool and has a maximum storage capacity of approximately 1,640 acre-feet. Flows from the reservoir are controlled with an intake tower structure with four sluice gates at various elevations, a fifth sluice gate is used to regulate flow from the intake tower into the outlet conduit. A concrete side-channel style trapezoidal chute spillway acts as the auxiliary spillway and is located on the left abutment. The control section of the auxiliary spillway is regulated by removable flashboards. The principal spillway consists of a reinforced concrete covered intake tower with a 48-inch diameter reinforced concrete outlet conduit. The intake tower is partially embedded in the upstream embankment slope. The intake tower has four sluice gates at various elevations connected to the reservoir. A fifth sluice gate is installed at the base of the riser to control the outlet conduit. Schnabel will actively work with the County to develop a solution to replace or rehabilitate the existing intake tower such that it meets your needs. A best-value solution will be developed considering the County's long-term needs and goals for water supply, water quality, ease of maintenance, and personnel and public safety. The Schnabel team has the unique expertise, experience, and depth of resources required for this project and has developed a proven approach to effectively and efficiently developing and implementing cost-effective solutions for dam and water supply projects, like the Lake Orange Intake Tower Rehabilitation Project. We have readied a team of professionals to handle the entire process from field investigations through permit approvals. Our team also has experience providing turnkey engineering services through construction and can provide these services once the project is ready for construction. The following subsections describe our team's approach and work plan to fulfilling the scope of services listed in the RFQ. This is a phased approach that involves ongoing collaboration with the County, ensuring the most appropriate intake solution is selected and developed on time and on budget. The bottom line is that the Schnabel team will work with Orange County to meet your objectives. 1. TASK 1 — KICKOFF AND FIELD INVESTIGATIONS 1.1 Historic Information Review, Kickoff Meeting, and Site Inspection Since Schnabel has already worked on Lake Orange Dam, we are familiar with the site and available information. To further familiarize our team with the project and inform the development Build Better.Together. 19 schnabel-eng.com 1. Qualifications / Lake Orange Intake Tower / 3 of intake replacement alternatives, we will review existing information on the dam, intake system, and watershed such as as-built drawings, original design documentation, previous inspection and investigation reports, operation and maintenance records, and surveys. In conjunction with our review of existing information, we will setup a kickoff meeting and site walk-through with the County. The purpose of this meeting and walk-through will be to finalize the project approach and field survey plans, observe the existing site conditions in more detail, and discuss key project milestones, operational considerations, site constraints, and other requirements. At the conclusion of the kickoff meeting, we will schedule the field investigations discussed below, the results of which will be used to inform the evaluation of intake rehabilitation or replacement alternatives and design development. 1.2 Site Survey Schnabel understands there was a site survey performed by CH Engineering (now Pennoni) to support erosion repairs on the upstream slope of the earth embankment in 2020. Schnabel will subcontract with Pennoni to update this baseline topographic survey to confirm the general geometry and evaluation of key features including the dam, intake tower, and select portions of areas surrounding the dam. A bathymetric survey of the reservoir area in the vicinity of the intake structure should also be performed as this information will help inform the evaluation of intake replacement alternatives, including options for control of water and stream diversion during construction, and the subsequent design. 1.3 Environmental Investigations Our environmental subconsultant, Three Oaks Engineering (Three Oaks) of Durham, NC, will research jurisdictional wetlands and waters within the project area. Based on our experience, the proposed improvements will impact jurisdictional waters but should qualify for a Nationwide Permit #3. Three Oaks will consult with the USACE and NC DEQ and North Carolina Division of Water Resources (NC DWR) to confirm that the proposed work is compatible with a Nationwide Permit #3. Three Oaks will also advise Schnabel on planning and design of the work to meet USACE, NC DEQ, and NC DWR permit conditions and to avoid the need for compensatory mitigation. 1.4 Underwater Investigation Depending on the anticipated scope of the intake tower rehabilitation or replacement based on the kick off meeting and discussions with the County, an underwater investigation of the existing intake tower and surrounding areas may be prudent to refine project details and reduce risk. Schnabel supported two previous dive inspections of the intake tower and will utilize information gathered during those and will only request an additional underwater investigation if needed. We routinely team with experienced underwater contractors to perform these types of investigations, and we anticipate that the investigation for this project could be completed cost-effectively in one day if it is needed. 1.5 Subsurface Investigation Depending on the anticipated scope of the intake tower rehabilitation or replacement based on the kick off meeting and discussions with the County, a subsurface geotechnical/geological investigation of the intake tower and surrounding areas may be needed to obtain information to support the alternatives analysis and design. Also, it is our understanding that the County intends to keep the reservoir at least partially full during construction of the intake tower rehabilitation/ replacement, this will require the installation of a temporary cofferdam around the intake tower work area to allow for the area to be dewatered. The subsurface investigation will also gather Build Better.Together. 20 schnabel-eng.com 1. Qualifications Lake Orange Intake Tower 4 .. ...... .............. data to support the design of temporary works like the cofferdam. If a subsurface investigation is deemed necessary, Schnabel will subcontract with a qualified geotechnical drilling firm to perform the subsurface investigation in coordination with Schnabel. It is likely that the subsurface investigation will need to be performed from a barge. Schnabel geologists and geotechnical engineers have experience with geotechnical drilling from a barge. Samples collected during the subsurface investigation will be sent to either Schnabel's soil and rock testing laboratory in Richmond, VA, or subcontracted to a more local laboratory based on which tests are required and schedule constraints. 2. TASK 2 — EVALUATION OF REHABILITATION AND/OR REPLACEMENT ALTERNATIVES (PRELIMINARY DESIGN REPORT) As discussed in the following sections, we will evaluate potential intake rehabilitation and/ or replacement alternatives that meet regulatory requirements and the County's objectives for the project. This alternatives evaluation will require various engineering analyses, design and construction considerations, and the evaluation of cost and multiple other critical qualitative factors. 2.1 Analysis 2.1.1 Hydrologic and Hydraulic Modeling In order to adequately layout and size the rehabilitated or replacement intake tower, it is critical to understand the hydrologic conditions in the watershed and the existing and desired hydraulic performance of the intake system. This analysis will consist of an evaluation of hydrologic parameters of the watershed such as rainfall, runoff curve number, and lag time to develop hydrographs to analyze the Lake Orange facility. Land cover data will be developed using both current aerial photography and zoning information; and based upon future build out, if desired. The site will be analyzed using the topographic survey information, field observations, and any historical data provided. A HEC-HMS hydrologic model will be developed that incorporates the runoff from the contributing watershed and the storage and hydraulics of the dam and impoundment. Based upon our analysis of existing conditions, we will model intake rehabilitation and/or replacement options that meet County and regulatory requirements for debris mitigation, water quality, and hydraulic performance. These analyses will also be used to develop potential control of water and stream diversion options for construction. 2.1.2 Structural Analyses Structural analyses of the rehabilitated or replacement intake system will be required, along with confirming that removal of the existing intake tower and construction of the rehabilitated or replacement intake tower does not substantially impact the stability of the dam. Our analyses will be performed based on existing data obtained from our document review and informed by the structural inspections performed. We will consider various loading conditions including normal pool, flood surcharge for unusual and extreme conditions, and seismic loading. 2.2 Temporary Measures Construction site access, control of water, and stream diversion during construction are often some of the most expensive and over-looked parts of any dam project. Safety for the on-site staff, the dam, and the downstream communities is paramount. For control of water and stream diversion, we will work closely with the County to understand your objectives, constraints, and tolerance for risk during construction, and we will develop control of water options for the County's review considering such factors as cost, constructability, and water supply impacts. We have extensive experience designing and implementing a wide variety of control of water solutions, and we will bring this expertise to your project to select the most appropriate solution for the County. Build Better.Together. 21 schnabel-eng.com 1 . Qualifications / Lake Orange Intake Tower 5 ... ................... 2.3 Concept Development and Reporting (Preliminary Design Report) We will use our extensive experience, information from field investigation(s), and analysis data discussed above to develop innovative, long-term solutions for the project that meet regulatory requirements, improve operation and maintenance, minimize impacts to the existing infrastructure, and streamline construction planning. Another consideration for the replacement intake system is instrumentation. We will coordinate with the County to develop instrumentation alternatives that improve operation, maintenance, security, and safety, and work with the existing data systems the County has. Schnabel will develop conceptual drawings (i.e., figures) for each intake rehabilitation/ replacement alternative presented. These figures will include a plan and typical section view of each alternative sufficient to show the intent and general layout. Preliminary engineer's opinion of probable construction costs (EOPCCs) will be developed for each alternative considering the factors discussed above and estimated quantities from the conceptual layouts. A Preliminary Design Report outlining the potential intake rehabilitation and/or replacement alternatives will be provided. The report will include the analysis of the existing conditions and alternatives, concept drawings, and preliminary EOPCC developed for each alternative. In addition to cost, the report will also include a comparison of the alternatives with respect to potential water supply impacts, construction schedule, temporary stream diversion and control of water, long-term operation and maintenance, aesthetics, potential permitting requirements and environmental impacts, and other qualitative factors. Following the issuance of this report, we propose to meet with the County to discuss the results of the alternatives analysis and discuss the path forward for design of the selected alternative. 3. TASK 3 — DEVELOPMENT OF CONSTRUCTION DOCUMENTS (DESIGN) After the County chooses a preferred intake rehabilitation or replacement alternative solution, we will begin detailed design and development of the of the construction and permitting packages. Most design projects of this size and scope include multiple design milestones. We will work closely with the County during the proposal development phase to define the desired milestones. At a minimum we propose at least one interim (e.g., 60%) design submittal to provide the County with a design progress set and the opportunity to provide formal review comments. We will also meet with the County to review the design documents prior to submission of the permitting packages to the regulatory agencies and issuance of the design and bid documents to prospective contractors. We also propose routine coordination calls with County throughout the design process to support decision-making and promote a more efficient design process. Design deliverables will include a design report, design drawings, technical specifications, an updated EOPCC, and an updated construction schedule estimate. The design report will present the design basis and the investigations and analyses performed to support the design. The drawings will include plans, sections, profiles, details, cross-references, and explanatory notes and scale sufficient for bidding and constructing the project. The technical specifications will be developed using the CSI format to delineate the technical requirements for the project work, materials, installation requirements, and acceptable tolerances. 4. TASK 4 — PERMITTING Our team has significant experience obtaining the approvals and permits for modifications like those that may be required for the intake rehabilitation or replacement at Lake Orange Dam. Though permitting is shown as a separate task in this SOQ, we propose that permitting be performed in parallel with design to avoid unnecessary delays and costs. As such, we will communicate with the various regulatory agencies throughout the design process so that they are not presented with any surprises, and they understand when they will receive the applications and County's desired schedule for implementing the improvements. During this phase or other phases, Build Better.Together. 22 schnabel-eng.com 1 . Qualifications / Lake Orange Intake Tower / 6 we can also assist the County in presenting to regulatory agencies, the public, and/or other stakeholders, as needed. Based on our review of the NC Dam Inventory, Lake Orange Dam is regulated by NC DEQ Dam Safety as a medium-size high hazard structure (ORANG-005). As a result, drawings, specifications, and a design report for the proposed modifications will need to be submitted to NC DEQ Dam Safety for their review and approval. We routinely prepare similar packages for NC DEQ Dam Safety and work to obtain their approval in a timely manner. Environmental 401/404 permitting will be provided by our subconsultant, Three Oaks. Three Oaks and Schnabel have a great working relationship and Three Oaks' project manager, James Mason, MS, PWS has extensive experience evaluating and permitting various projects including dam and reservoir projects. As indicated above, we anticipate that the proposed modifications to Lake Orange Dam can be permitted as maintenance activities; therefore, we anticipate this permitting process will be straightforward and efficient. In addition to NC DEQ Dam Safety approval, it is possible that an erosion and sediment control permit will be required depending on the extent of the proposed modifications and the associated land disturbance. If necessary, this plan will be prepared for submission to Orange County or the regional NC DEQ office. 5. TASK 5 — BIDDING We provide bid phase support services for the majority of our dam and dam-related projects, and our team proposed for this project can provide these services to assist the County with bidding the project. These services typically include: • Preparing front-end contract documents using client-provided templates or EJCDC templates, • Facilitating a pre-bid meeting and site visit, • Responding to bidder questions and preparing bid addenda, • Attending the bid opening and reviewing construction bids, • Providing a recommendation of award, and • Preparing conformance documents based on any changes identified during the bidding process. 6. TASK 6 — CONSTRUCTION PHASE SERVICES We can also provide a range of construction phase services depending on the County's desired level of support. We routinely provide full construction contract administration services, such as facilitating meetings, reviewing and approving pay applications, reviewing and approving submittals, preparing field orders and change orders, and resolving other construction coordination issues as required. Dam and intake modification projects such as this also typically require a high level of engineering support and observation during construction, and the involvement of the original design team is critical to ensuring that the design intent is met and the work is completed in accordance with the approved construction documents, as required by NC DEQ Dam Safety. As such, we also routinely provide a full-time or part-time Resident Project Representative (RPR) to oversee the construction and manage the quality assurance effort, and we can provide these services for this project to the extent the County desires and to meet the requirements of the NC DEQ Dam Safety permit. 7. TASK 7 — PROJECT CLOSEOUT Upon construction completion, we will prepare the project close-out documents required by NC DEQ Dam Safety, including the record drawings, completion report, and Operation and Maintenance manual. We will also provide services for construction close-out including a final walk through with the County and the contractor, development of punch list(s), review of the final pay application, and processing of contractor closeout submittals. Build Better.Together. 23 schnabel-eng.com 1. Qualifications / Lake Orange Intake Tower / 7 8. SCHEDULE As shown below, we have developed a preliminary schedule estimate for completion of this project. The site visit and field investigations will commence upon notice-to-proceed (NTP), and the evaluation of intake rehabilitation and/or replacement alternatives will begin during or immediately following the field investigations. The schedule for design will ultimately depend on the design milestones and intake rehabilitation/replacement alternative selected by the County; however, in our experience, the design schedule estimate shown below is reasonable for a project of this size and scope. The schedule for permit approvals is somewhat beyond our control; however, as discussed under Task 4 above, we believe early and frequent collaboration with the regulators will allow for a smooth and efficient permitting process. The schedule for construction will depend on the selected contractor and the final scope of the improvements. The bottom line is that we will work closely with the County to make sure the project is completed within your timeline.

Innovative Factors ...................................................................................................................................................................................................................................................................... Schnabel has extensive experience with federally funded dam design and construction projects, in addition to other type of infrastructure projects receiving federal funding in which Schnabel has been involved. Within the past five years alone, Schnabel has managed the design and construction of two Federal Emergency Management Agency (FEMA) funded dam remediation projects in South Carolina, prepared designs and provided construction phase engineering for numerous NRCS funded dam rehabilitation projects in various states, performed engineering designs for US Bureau of Reclamation (USBR) owned projects, and participated in the review of the USACE Dam Safety Program. Schnabel has also provided design and construction phase engineering for dam engineering projects receiving funds from various state agencies. In addition, Schnabel routinely hires and consults with former federal employees, which provides us with a unique perspective and understanding of federal processes. Through this extensive recent experience and knowledge obtained from former federal employees, Schnabel continues to expand our unparalleled knowledge and understanding of the processes that are utilized by federal agencies as projects progress from design through construction. This vast knowledge base allows projects to be completed on-time and on-budget without interruption to the Owner. Specific recent examples of projects, which receive either federal or state funding, are highlighted below. »Schnabel has also worked with the Town of Lake Lure, NC to receive two cycles of dam rehabilitation funding through the FEMA Rehabilitation of High Hazard Potential Dams (HHPD) Program. The funding is being used to design and construct a new reservoir drain through the base of this 120-foot-tall, concrete multiple arch-buttress dam. »After Hurricane Florence, Governor Cooper established the North Carolina Office of Recovery and Resiliency (NCORR), a division of the N.C. Department of Public Safety, to provide disaster recovery programs statewide and help communities and disaster survivors recover and rebuild smarter and stronger. In late 2017, the Department of Environmental Quality (NC DEQ), Division of Energy, Mineral and Land Resources (DEMLR), was awarded a $500,000 grant to gather necessary information and perform hydrologic and hydraulic (H&H) analysis on the dams located within the Neuse River Basin to better understand hydraulic capacity and performance of the structures during storms like Florence and be better prepared for future hurricane events. ))With Schnabel's assistance, Aiken County, South Carolina received federal funding from FEMA to remediate Langley Dam, a century old structure that was in jeopardy of failing. The funding, which equated to approximately 50 percent of the construction cost, required unique management on Schnabel's part in that all pay requests from the contractor had to be allocated between grant funding and non-grant funding. Through diligent recording keeping and understanding of the eligible portions of the project, each pay request was reviewed and approved by Aiken County and the funding agency without hesitation. »Schnabel has performed numerous assessments, planning studies, detailed designs, and construction phase engineering on the behalf of the state and local conservation districts and the NRCS. Many of these projects were funded, at least partly, by the NRCS and involved cost- sharing agreements between federal agencies and local sponsoring organizations. As required by the agreements and requested by the owners, Schnabel assisted with the management of the projects and progress and budget tracking for cost-sharing purposes.
